Can't get an external fan controller to work

Fan total - 2x120 1x140 1x200 1x230

I don't really care to control the 200 and 230. I mainly want it for the others.

So originally I bought a BitFenix Recon open box from Canada Computers. It was the only one left so I took a chance. So when it powers up, the fans are spinning faster then the settings and slows down. Once it slowly creeps down to the speeds I have set, it beeps a few seconds later and starts spinning fast again and slowing down, repeat times infinite. At first I thought it was the controller. I missed my 7 day open box return period, chalked it up as a mistake and just bought the NZXT sentry 3 thinking it couldn't possibly have the same problem. It does. I've tried other things with the Sentry 3 like only using 3 and even just 1 fan connected but it still resets with a beep and powers the fans back up to full speed. Any ideas whats up?

How are the fans connected?

None have molex connectors. I can tell you that. All 5 fans were plugged straight into the extenders from the controller.
The only other thing plugged into the sata power cable from the psu is the h105.

Could you, please explain where the beep comes from, and how the fan runs at full speed, since it is connected only to the fan controller, that has nothing to do with the motherboard?

Clicked the solution thing by accident... The beep comes from the fan controller. Both had a beep. The controllers make the same beep every time you turn your system on but there is a button to turn the sound off and then it would just do it without beeping.
When it resets they may not be at "full" speed but its like when you turn your system on and the fans spin a little faster and then slow down... All my computers have done this at least.

Some kind of odd power problem? Have you tried a different power connector on the fan controller. Try all the fans each individually to narrow down the chance of a short somewhere causing it.
